Abstract
The utility model discloses an emergency brake auxiliary device, which is provided on the chassis of the vehicle. The utility model comprises the components such as a hydraulic supporting bar, friction disks, a friction disk connecting bar, a force-return spring and the like, characterized in that the root of the hydraulic supporting bar is communicated with a brake oil pump, the end portion is connected with the friction disk connecting bar, the friction disk connecting bar is rotatably connected with the chassis of the vehicle, and one end of the force-return spring is connected with the friction disks, the other end is provided on the chassis of the vehicle, the friction disks are strained to cling to the chassis of the vehicle. The auxiliary device can increase the friction force when doing emergency brake, the brake distance of the vehicle in emergency state is made to be shortened markedly, and simultaneously one or two powerful supporting points are provided to the vehicle, and thereby the overturn of the vehicle, which is caused by strenuous braking, is avoided.
Description
Technical field
The utility model relates to a kind of self-propelled vehicle emergency brake auxiliary device.
Background technology
In the existing motor-rehicle braking system, friction force acts on the ground-surface tread of tyre that has only, because limited with ground-surface contact surface, so braking distance generally all reaches more than 10 meters, because action of inertia can make the vehicle meeting unbalance, very easily cause roll-over accident simultaneously.At this present situation, people have also found out many counter-measures, a kind of automobile emergency brake auxiliary device is disclosed as Chinese patent 912332271, its characteristic is to have an iron plate case to be fixedly mounted on the front upper place of automobile back wheel, one tri-prismoid is housed in the iron plate case, but during emergency braking, this tri-prismoid is placed on wheel and comes to stop vehicle to move ahead.This technical scheme has solved the brake problem to a certain extent, but when the vehicle fast running, adopts the emergency brake of this kind mode, is very easy to cause roll-over accident.Also have Chinese patent 200520070420.3 also to disclose a kind of automobile emergency brake auxiliary device, its feature is the flexible cylinder of the air pressure on car chassis, and high pressure gas holder matching used with it, the piston arm front end of the flexible cylinder of air pressure is equipped with friction plate, and emergency brake is to rely on the friction plate brake.This technical scheme than previous more science a bit, but it adopts the air pressure cylinder that stretches, and has great potential safety hazard, and is slow such as speed of response, easy detonation of cylinder or the like.
The utility model content
Technical problem to be solved in the utility model is how a kind of emergency brake auxiliary device is provided, and it can increase vehicle and ground-surface area of contact by actv., increases friction force, avoids vehicle to cause the danger of toppling because of violent brake.
The technical matters that the utility model proposed is to solve like this: construct a kind of emergency brake auxiliary device, it is located on the vehicle chassis, comprise parts such as hydraulic pressure strut bar, friction lining, friction lining connecting rod and return spring, it is characterized in that: described hydraulic pressure strut bar root and brake oil pump UNICOM, the end is connected with described friction lining connecting rod, and described friction lining connecting rod and vehicle chassis are rotationally connected; Described return spring one end is connected with friction lining, and the other end is arranged on the vehicle chassis, and the tension friction lining is attached on the vehicle chassis it.
Emergency brake auxiliary device provided by the utility model can be provided with one or two at vehicle chassis, when emergency brake, the brake oil pump provides the pressure that continues increasing, friction lining can continue to increase reposefully friction force under the effect of hydraulic support shaft, braking distance when making vehicle shorten the emergency state greatly simultaneously for vehicle provides one or two strong strong points, avoids vehicle to topple because of violent brake.
Description of drawings
Fig. 1 is the structural representation of self-propelled vehicle emergency brake auxiliary device provided by the utility model;
Fig. 2 is the running condition figure of self-propelled vehicle emergency brake auxiliary device provided by the utility model.
Wherein, 1, return spring, 2, vehicle chassis, 3, the friction lining connecting rod, 4, the hydraulic pressure strut bar, 5, friction lining.
The specific embodiment
Below in conjunction with accompanying drawing self-propelled vehicle emergency brake auxiliary device provided by the utility model is elaborated.
As shown in Figure 1 and Figure 2, this device is located on the vehicle chassis, comprise parts such as hydraulic pressure strut bar 4, friction lining 5, friction lining connecting rod 3 and return spring 1, wherein hydraulic pressure strut bar 4 roots and brake oil pump UNICOM, the end is connected with described friction lining connecting rod 4, and friction lining connecting rod 4 is rotationally connected with vehicle chassis 2, and return spring 1 one ends are connected with friction lining 5, the other end is arranged on the vehicle chassis 2, and tension friction lining 5 is attached on the vehicle chassis 2 it.
This device is because hydraulic pressure strut bar 4 and existing brake oil pipe UNICOM, and during emergency brake, the hydraulic pressure strut bar stretches fast under the effect of oil pump, and it is sagging to promote connecting rod 2, makes friction lining 5 kiss the earths, thereby reaches the purpose of steady brake; But when removing the emergency brake state, when promptly the brake solution pump pressure reduced, hydraulic pressure strut bar 4 shrank, and friction lining 5 recovers normally promptly to be hidden on the vehicle chassis under the effect of return spring 1.
